The design and laser adjustment of the resistive element optimises the limiting element voltage of the resistor. The terminations have an electroplated nickel barrier and tin finish. This ensures excellent `leach' resistance properties and solderability. Marking Terminations The body protection is resistant to all normal cleaning solvents suitable for printed circuits. The chips are not marked and the relevant information on type, value, tolerance date code and quantity are recorded on the reel. The chips are supplied with wrap-around terminations suitable for soldering. Consult factory for alternative termination options.

For soldered resistors, the joint temperature should not exceed 110C. This condition is met when the stated power levels at 70C are used. HVC resistors are ideally suited for handling by automatic methods due to their rectangular shape and the small dimensional tolerances. Electrical connection to a ceramic substrate or to a printed circuit board can be made by reflow or wave soldering of wrap-around terminations. The PCB layout should avoid tracks running between the HVC mounting pads, as this would compromise the LEV. Wrap-around terminations provide good leach properties and ensure reliable contact. Due to the robust construction, the HVC can be immersed in the solder bath for 30 seconds at 260C. This enables the resistor to be mounted on one side of a printed circuit board and wire-leaded components applied on the other side. The LEV stated applies to operation at sea-level pressure, in a non-condensing atmosphere and non-contaminating environment. Voltage derating should be applied if low pressure, high humidity or contamination may be encountered. The termination clearance dimension (B) should be used in conjunction with the creepage limit applicable to the circuit application in order to determine the derated LEV. HVC resistors themselves can operate at a maximum Packaging HVC Resistors are supplied taped and reeled as per IEC 286-3.
