Spiral chip inductors are manufactured on quartz (SiO2), 20 mils thick, for lowest capacitance and highest SRF and PRF. The LX2500Q20-L07-31nH spiral chip inductors are manufactured on quartz (SiO2), 20 mils thick. These devices can be used over the full military temperature range -55°C to +125°C. Quality and workmanship is per MIL-S-883. Devices are 100% tested, visual inspected and packaged in waffle packs.Spiral Chip Inductors Lab kits are available from stock: L-Kit PRODUCT DESCRIPTION AND SHORT APPLICATION NOTE The LX2500Q20-L07-31nH Series of spiral chip inductors are designed to be used in chip and wire hybrid circuits as RF choke in power supplies and microwave circuit resonant elements. When used as chokes, a modest Q is desirable while in oscillators Q has to be as high as possible. U.S. Microwaves advanced thin film technologies allow for an important reduction of the DCR max, which translates into an increased Q. For spirals with w+s=25µm, Q values between 25 and 30 are obtained which represent a better compromise between the two applications. For lowest capacitance and higher self resonance, the LX2500Q20-L07-31nH spiral chip inductors are manufactured on 20 mil thick quartz (SiO2) substrates. Application notes AN 102, AN 112 and AN 113 are describing assembly methods for best performance. Manufactured with 99.9% pure gold, the spiral inductor chip does not need any protection and can operate even in hostile environments. Designed and manufactured by US Microwaves in 1990 for military and industrial applications, the spiral chip inductors now can find their place in optoelectronic and wireless consumer products as well. TECHNOLOGY DESCRIPTION: SEMICONDUCTOR-THIN FILM MANUFACTURING All thin film microwave products are manufactured using advanced semiconductors and thin film technologies including ultra-stable and self passivating Tantalum Nitride resistors, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. US Microwaves employs proprietary thin film technologies for deposition of a wide range of resistive films with sheet resistance films from 1W/sq to 10,000W/sq. All US Microwaves products are available in die form and are ideal for high reliability hybrid and multi chip module applications. All US Microwaves products are manufactured using GOLDCHIP TECHNOLOGY™ a trade mark of Semiconix Corporation.
