Like our other ceramic chip inductors, they feature outstanding selfresonant frequencies and excellent Q values. Most values are available in 2% inductance tolerance. With current ratings as high as 1.8 A, Coilcraft’s 0402PA wirewound chip inductors are ideal for power amplifiers in TDMA, CDMA, GSM and other wireless applications. Compared to our standard 0402CS Series, they can handle up to 65% more current and have half the DC resistance. These inductors are perfect for use as an RF choke for the power supply, the LC tank between ampli- Coilcraft **Designer’s Kit C373** contains samples of all 5% inductance tolerance parts.

When ordering, specify **tolerance, termination** and **packaging** codes: **0402PA-8N2XJLW** **Tolerance: G** = 2% **J** = 5% - **Termination: L** = RoHS compliant silver-palladium-platinum-glass frit - **E** = Halogen free component. RoHS compliant silverpalladium-platinum-glass frit terminations. Special order: **T** = RoHS tin-silver-copper (95.5/4/0.5) or **S** = non-RoHS tin-lead (63/37) - **Packaging: W** = 7″ machine-ready reel. EIA-481 punched paper tape (2000 parts per full reel). - **U** = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter W instead. 2. Inductance measured at 250 MHz using a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286 impedance analyzer. 3. Tolerances in bold are stocked for immediate shipment. 4. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture. 5. For SRF >6 GHz, measured using an Agilent/HP 8722ES network analyzer and a Coilcraft SMD-D test fixture. For SRF £6 GHz, measured using anAgilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. ## **Core material** Ceramic **Environmental** RoHS compliant, halogen free optional **Terminations** RoHS compliant silver-palladium-platinum-glass frit.
