Isolated inductor network Important reduction of the DCR High quality factor High SRF, PRF High Q oscillators Filters RF choke in power supplies The Lxx-xxnH-20Q Series of chip inductors are designed to be used 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's advanced thin film technologies allow for an important reduction of the DCR max, which translates into an increased Q. For spirals with w+s=25m m, Q values between 25 and 30 are obtained which represent a better compromise between the two applications. The dimensions of the die are 0.050"x0.050"x0.020". The Lxx-20Q inductors are manufactured on quartz (SiO2), 20 mils thick. Semiconwell manufactures passive network components, integrated active and passive devices, resistor networks, capacitor networks, schottky and zener diode networks, and npn, pnp transistors arrays that perform the following functions: series and parallel linear and nonlinear GTL, AC, Diode, Thevenin termination networks, precision thin film resistor capacitor networks (RC networks), isolated, bussed resistor networks including zero ohms jumper arrays, voltage divider networks, resistor networks for audio applications, EMI, RFI and ESD zener clamped diodes and transient voltage suppressors networks, EMI/RFI filter networks and clock terminations. Semiconwell's proprietary semiconductor technology, advanced thin films processes, in house assembly and packaging technologies allow manufacturing of flip chip CSP chip scale and MLF molded lead frame surface mount integrated passive networks that include unprecedented large capacitors >1microfarad (1µF) and giga ohms resistors (GW).
