BCR www.vishay.com Vishay Electro-Films Thin Film, Back-Contact Resistor FEATURES • • • • • • • • • 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. Wire bondable Only one wire bond required Small size: 0.020 inches square Resistance range: 10 to 1 M Oxidized silicon substrate for good power dissipation Resistor material: Tantalum nitride, self-passivating Moisture resistant Case size: 0202 Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 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 eutectically 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.)
