PSC

PSC Vishay Electro-Films Spiral Chip Inductor FEATURES • Wire bondable Product may not be to scale • Small chip size: 0.050 inches square • Alumina substrate • Inductance up to 150 nH • Inductor material: Thin film gold 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. 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. VALUES AND TOLERANCES TYPE S Single Bond Q at 1 MHz Tolerances Steps Custom values/sizes available. Quartz substrate available for higher Q.
