RF Wirewound Chip Inductors Overview
This datasheet provides comprehensive information about high-performance RF Wirewound Chip Inductors designed for high frequency applications. These inductors boast a monolithic ceramic body with wire winding, optimized for high-Q, high-frequency performance across various RF applications.
Key Features and Applications
The inductors come in compact sizes and are compatible with high volume production, thanks to their tape and reel packaging. They are suitable for a range of applications, including:
CELLPCS Modules, Broadband Components, RF Transceivers, Cable Modem, Bluetooth,
Wireless LAN, RFID, Cordless Phone, Computer Peripherals, and ADSL. The chips feature a nickel barrier and are plated with gold for ceramic core types (all 0402, all 0603, and most 0805 types), or with 100% tin for ferrite core types (0805 size, 470 nH and higher).
Product Range and Characteristics
| EIA Size (mm) | Inductance Range (LRange) | Quality Factor (Typ.) | Self-Resonant Frequency (SRF, Typ.) | Operating Temperature Range |
|---|---|---|---|---|
| 0402 (1005) | 1.0 – 120nH | 55 (900 MHz) | >11 GHz (1.0 nH) | -40°C to +125°C |
| 0603 (1608) | 2.0 – 470 nH | 60 (900 MHz) | >13 GHz (2.0 nH) | -40°C to +125°C |
| 0805 (2012) | 2.2 – 10,000 nH | 60 (500 MHz) | >11 GHz (2.2 nH) | -40°C to +125°C* |
*Ferrite core types have a different operating temperature range of 40°C to +85°C.
Mechanical Characteristics
The inductors are available in three sizes: 0402 (1.00 x 0.55 x 0.50 mm), 0603 (1.60 x 1.05 x 1.05 mm), and 0805 (2.00 x 1.25 x 1.20 mm) with corresponding inch dimensions provided.
Ordering Information
To order, specify the device (Inductor), size code (07 for 0402, 14 for 0603, 15 for 0805), type, value, tolerance, termination, and packaging. Marking and packaging options include no marking for all 0402 and 0603, value marking for all 0805, with tape and reel packaging in various reel sizes or bulk.
Selection Chart
The selection chart on the next pages lists all offerings, including inductance values, tolerances, and rated currents for the 0402, 0603, and 0805 sizes.
