SLR (Single Layer Resistor Carrier) networks are offered to provide the user with a leadless device that maximizes board density
while maintaining tight ratio tolerances and TCR tracking. Pads are provided top and bottom connected by edge castellations for
ease of visual solder joint inspection. Resistors can be covered with Vishay Electro-Films (EFI) proprietary thermal set plastic
for physical protection or left uncoated to facilitate user trimming.
SLR’s are provided with 0.050 inches standard contact spacing; however, 0.025 inches contact spacing is also available. The
standard contact metallization is gold flash over nickel plate. Solder coated contacts can be provided if preferred. Custom
configurations, values, and tolerance combinations are available with fast turnaround.

The SLR construction allows for a wide selection of special sizes and shapes with rapid turnaround and low NRE costs. The holes
for the edge castellations are laser drilled into a multiple-up, large area substrates in-house prior to metallization. This permits
new configurations with only laser software and a mask set.
Custom parts can be provided with combinations of features listed:
1.
2.
3.
4.
5.
Any combination of resistor values between 100 Ω and 100 kΩ in the standard sizes.
Custom resistor network patterns (no crossovers).
A wide variety of rectangular sizes and shapes with contact pads on two to four sides.
Pad center-to-center spacings from 0.025 inches (0.635 mm) and larger.
Uncoated to permit customer trimming.
