Product may not
be to scale
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.
