PSC

Vishay Electro-Films

Spiral Chip Inductor

The PSC Chip Inductors offer the best combination of size

and value available. Generally custom built to specific value

requirements, two versions are offered here.

These chips are manufactured using Vishay Electro-Films

(EFI) sophisticated Thin Film equipment and manufacturing

technology. The PSCs are 100 % electrically tested for

inductance and Q.

FEATURES

• Wire bondable

• Small chip size: 0.050 inches square

• Alumina substrate

• Inductance up to 150 nH

• Inductor material: Thin film gold

APPLICATIONS

Primary application is in microwave circuits as resistant element or as choke in power supplies. High self-resonance is important

for choke applications and achieved by reducing capacitance between turns by physically increasing space between spiral lines.

Multi tap coils are available for wire bond tuning but since inductors are very sensitive to pattern width/spacing and metallization

thickness almost all are custom built to specification desired.

Custom values/sizes available. Quartz substrate available for higher Q.
