Construction

A metal film is deposited onto a high quality ceramic former.

Nickel-plated steel caps are force fitted to the former and

termination wires are welded to the caps.

The resistor is adjusted to value by a helical cut in the film

and the body is protected with a specially formulated epoxy

coating.

Terminations

Material Solder coated copper wire

Strength The terminations meet the requirements of

IEC 68.2.21.

Solderability The terminations meet the requirements of

IEC 115-1, Clause 4.17.3.2.

Precision Metal

Film Resistors

RC series

Marking

Type reference, TCR code, resistance value and

tolerance code.

The resistance values conform to IEC 62.

Solvent Resistance

The body protection and marking are resistant to all normal

industrial cleaning solvents suitable for printed circuits.

Performance Data

Note: *An 0.01 ohm addition to be added to the performance claims of all resistors <10R.

** All products within the specified approved range meet EN140101 and CECC40101 requirements.

Precision Metal Film Resistors

Application Notes

Matched Sets

TT Electronics has many years’ experience in the supply of

matched sets of precision resistors.

Resistors can be supplied matched for tolerance and TCR

down to ±0.02% and ±2ppm/°C.

Packaging

RC55 and RC65 standard packing is in tape, as shown below,

whilst RC70 is bulk packed.

Taped resistors on reel or loose

components can also be supplied by special request.

For product released to EN140101 or CECC40101, state on order the relevant number and style.

Examples: RC55Y-31K6BI EN140101-806 B

RC55Y-31K6BI CECC40101-004 JY

For CECC 40101-804 the TCR codes T and E relate to 15 and 25ppm/°C and are coded in the MPN as Y and D respecvely. Also an addional

sux -804 is added aer the Finish, Screening & Packing code, and, in the case of Pb-free, this code (I) is omied. Example: RC65Y-31K6B-804 CECC 40101-804BT
