SPIRAL CHIP INDUCTORS LX3000Q20-L07-31nH FEATURES Spiral chip inductors are available in 2 different die dimensions: For 1 turn to 21 turns series the die size is 0.030"x0.030"x0.020". For 1 turn to 5.5 turns the spiral chip inductors are also available in die size of 0.030"x0.030"x0.020". The L07-31nH spiral chip inductors are manufactured on quartz (SiO2), 20 mils thick. APPLICATIONS 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 Application note: AN 102 PRODUCT DESCRIPTION The 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. Semiconwell 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 L07-31nH spiral chip inductors are manufactured on 20 mil thick quartz (SiO2) substrates. Application note AN 102 describes the recommended assembly for best performance. MICROWAVE APPLIED THIN FILM PRODUCTS MANUFACTURING PROCESS DESCRIPTION All thin film microwave products are manufactured using advanced 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. Semiconwell employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1W/sq to 10,000 W/sq. All Semiconwell products are available in die form and are ideal for high reliability hybrid and multi chip module applications.

SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION

Integrated passive networks are manufactured using advanced 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 resistor technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. Semiconwell employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1 W/sq to 10,000 W/sq. All Semiconwell's products are available in die form and as KGD, known good die and are ideal for high reliability hybrid and multi chip module applications. Besides thin film resistors, Semiconwell integrates capacitors, Schottky diodes, Zener diodes and transistors. Integrated passive and active networks are manufactured using Semiconwell's in house high reliability semiconductor manufacturing processes. All semiconductor devices employ precision doping via ion implantation, silicon nitride junction passivation, platinum silicided contacts and gold interconnect metallization for best performance and reliability. MNOS capacitors and Tantalum Nitride resistors are easily integrated with Schottky diodes to provide complete standard and custom RCD solutions. In die form, these products are ideal for hybrid and multi chip module applications. In packaged form, these products are the best solution where space and weight are a concern.
