Spiral chip inductors are available in 3 different die dimensions: - For 1 turn to 21 turns series the die size is 0.050"x0.050"x0.020". - For 1 turn to 12 turns the die size is 0.030"x0.030"x0.020". - For 1 turn to 8 turns the die size is 0.025"x0.025"x0.020". Spiral chip inductors are manufactured on quartz (SiO2), 20 mils thick, for lowest capacitance and highest SRF and PRF. The LX2500Q20NH-L1.5T-1nH 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
The LX2500Q20NH-L1.5T-1nH 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 LX2500Q20NH-L1.5T-1nH 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.
