All Content Copyright (c)2000 KRL Bantry The Company - The Company - History - Profile KRL Electronics, a division of Bantry Components, Inc., is a thrity-one year old company which was purchased in 1985, by Bernard J. Perry, Sr., a resistor pioneer, and sold to Bernard J. Perry, Jr., in 1992 as a continuation of the Perry's commitment to the local community and the resistor industry. KRL offers precision and power wirewound resistors on a worldwide basis and is known worldide as a supplier of quality components with on-time delivery. The KRL customer base includes: the computer, power supply, health, avionics, instrumentation, telecommunications and space industries. We are proud of our global reputation and worldwide recognition. By offering a commitment to manufacturing quality, continuous renewed product design and innovation, customer service and a "can-do" attitude, KRL continues to earn and maintain customer and vendor loyalty. Our roots go back to 1948 when Mr. Perry Sr. opened the Daven Company as General Manager, and his subsequent founding of RCL Electronics in 1960, from which no fewer than four "spinoff" resistor companies were born. Two companies are local to New Hampshire, KRL being one of the two. RCL employed over 600 employees locally under the administration of Mr. Perry Sr., and eventually went down to less than 40 employees after Mr. Perry Sr. retired in 1969. Under the direction of the Perry family, RCL was known to be the world's leader in Precision Wirewound Resistors, both for sales and innovation. Mr. Perry came out of retirement in 1985, recruited Mr. Perry Jr., and purchased KRL Electronics, Inc. Starting with 47 employees and $700,000 in annual sales, KRL Electronics, division of Bantry Components, Inc. has grown from 47 to 110 employees; from 1 shift to 2 shifts. With added capacity through automation it is believed that the headcount will increase to 125-140 employees in the near future. Over the past sixteen years, KRL has maintained an aggressive approach to the migration of electronics from "through-hole" component printed circuit board (PCB) mounting to the new "SMT" surface-mount configuration for wirewound resistors. Facility expansions in 1998 saw a 214% increase in manufacturing space from 7,000 square feet to 17,000 square feet. The company began using two shifts in 1993 in order to delay physical plant expansion. Administration, Sales, Marketing, Finance, Engineering, Purchasing, Personnel, Shipping, Receiving, Warehousing, and Manufacturing functions are all housed in our 17,000 square foot plant. Manufacturing technologies employed by KRL include: coil winding, resistance welding, percussive arc welding, resistance trimming calibration, thermoset transfer molding, epoxy and cement potting, conformal coating, hermetic sealing, lead stamping and lead forming. Laboratory facilities provide the capability for: burn in, life test, thermal shock, moisture resistance, and temperature coefficient testing to monitor resistor function, quality and design. A fully functional machine shop offers milling, grinding, welding, metal heat-treating and lathe work support manufacturing and design functions. In Q3-1993 the entire manufacturing facility was redesigned and renovated to create a better workflow. KRL received ISO-9001 approval in the 4th quarter of 1997. The maintenance of this approval focuses on "quality at the source," a philosophy of building quality in from the beginning of the manufacturing process rather than depending on inspection for quality at the end of the process. This approval is a requirement for selling in The European Economic Community, and is fast becoming required by the larger US manufacturers. Employees KRL's employees number approximately 110, many of whom have been with KRL for over 15 years. Several KRL employees' careers date back to RCL and employment under Mr. Perry Sr., for up to 40+ years. The knowledge base of KRL's employees is extensive, with a tremendous level of cross training in the many resistor-manufacturing processes. The State of New Hampshire-Business Visitation Program opened the door for KRL to participate in various programs involving DRED, DES, the New Hampshire Job Training Council, and the OSHA, including the OSHA safety section's "Consultation Program". Mr. B.J. Perry Jr. was appointed to Governor Merrill's Worker's Compensation Study Committee because of his devotion to his employees, his commitment to worker's safety, and the company's prospects for future employment and company expansion in New Hampshire. Future A. New products/Applications including additional Surface Mount Components 1. Surface mount wirewounds, capable of low values and high accuracy, and used in small computer peripheral equipment and in laptops. Exported from NH to the world. 2. Pulse-withstanding resistor products used in telecommunications industry (phones and switching circuits). Guard against damage caused by lightning surges or power crossovers. Used in new fiber optic systems being used by old Eastern Block countries updating their communications systems in the former East Germany, and the republics of the former Soviet Union, etc. 3. Low Ohms current shunt values to .0001 ohm -- used by manufacturers of smaller generating equipment, including generators intended as home back-ups to existing power systems in developing countries. - The Company - History - Profile KRL/Bantry Components History Formed in 1970 and located on Bridge Street Primary product line: Precision Wirewounds and Temperature Sensors.

NOTE: If you order a resistor by specifying only the style, Resistance, Value and Tolerance... KRL will manufacture to standard specification unless otherwise indicated.

See Temperature Coefficient Chart above. (5) Resistance Value... Specify resistance in ohms. Most values are specified via a 4-digit code: the first three digits are significant figures and the fourth digit is the multiplier, i.e., the number of zeroes to follow (e.g., 250K = 22503; 2.55K = 2551; 255 = 2550). For values under 100 , `R' is used for the decimal (e.g., 39 = 39R0; .025 = R025) For values with more then 3 significant figures, use additional digits as necessary (e.g., 255.5K = 25552; 2.555K = 25550) (6) Tolerance... See Tolerance Order Code above. Exact interchangeability is not implied, as there are some minor differences which may exist.

When used in a "Kelvin" configuration, applying current through two opposite leads and sensing voltage across the other two leads, the resistance and temperature coefficient of the leads are effectively eliminated. This results in lower TC's and lower self-heating drift than with two terminal resistors, and eliminates the need for connecting to the leads at precise "test points", allowing tighter tolerances to be held as well.

FPR Resistors provide reliable and accurate blow characteristics. The FPR resistors fail in an open mode. The resistors are available in ohmic values from .22 to 100K , and wattage sizes from 1/2 to 3 watts. Various telephone power line and tip & ring circuits utilize the FPR resistor to protect sensitive parts from lightning strike surges. Other circuits that would benefit from these fusible resistors are inputs that may be exposed to line voltage faults or power supplies that need current limiting with a safe, nonflame failure mode. Since each circuit has different and custom requirements, KRL/Bantry will work with your engineering staff to help choose the correct part for your application.
