Product may not be to scale
The Back Contact Resistor (BCR) series single-value
back-contact resistor chip is one of the smallest chips
available.
The BCR requires only one wire bond thus saving hybrid
space.
The BCRs are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology. The BCRs are 100 % electrically tested and
visually inspected to MIL-STD-883, method 2032 class H
or K.

APPLICATIONS
Vishay EFI BCR resistor chips are widely used in hybrid
packages where space is limited. The bottom connection is
made by attaching the back of the chip to the substrate
either eutectic or with conductive epoxy. The single wire
bond is made to the notched pad on the top of the chip. (The
other rectangular pad on the top of the chip is a via hole, a
low-ohmic contact connecting the resistor to the bottom of
the chip.)
