Document 347 -1 Chip Inductors – 0402PA Series (1005) 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- Part number1 0402PA-0N8X_L_ 0402PA-1N9X_L_ 0402PA-3N4X_L_ 0402PA-3N5X_L_ 0402PA-5N8X_L_ 0402PA-6N2X_L_ 0402PA-8N2X_L_ Inductance2 (nH) 0.78 1.9 3.4 3.5 5.8 6.2 8.2 Percent tolerance3 5 5,2 5,2 5,2 5,2 5,2 5,2 fier and antenna and in the amplifier bias circuit. Like our other ceramic chip inductors, they feature outstanding selfresonant frequencies and excellent Q values. Most values are available in 2% inductance tolerance. 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 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. 6. DCR measured on a micro-ohmmeter. 7. Current that causes a 15°C temperature rise from 25°C ambient. 8. Electrical specifications at 25°C.
