4 Line Ferrite Common Mode Power Chokes COMMON MODE Steward’s multi-line ferrite common mode power / data filter products provide the most economical EMI filtering available for common mode noise. They provide EMI suppres sion for groups of conductors such as power traces, and for high speed input/output circuitry (including network and storage subsystems). They exhibit high frequency impedance essentially independent of DC bias current. Protected by one or more of the following US Patents: 5,455,552 and 5,568,111 Features: ·High current carrying capability (10 amps continuous operation) ·Can be used as multi-turn device to multiply impedance ·With two turns, up to 800 ohms impedance at 300 MHz. ·Available in both thru-hole (B) and surface mount (R) versions ·The most economical common mode filter available for filtering groups of signals ·Parts available in broad band and high frequency materials Applications: ·Filtering DC power on PC boards, especially in applications of greater than 3.0 amperes ·Filtering common mode EMI on high speed differential lines such as network and SCSI subsystems ·Cost sensitive designs ·Applications where low DCR is needed. Part & Test Specifications: ·Maximum current ratings ( I MAX ) are determined by testing to a maximum temperature rise of 40oC with continuous operating current. ·Board level components are rated up to a maximum of 75 volts ·Part performance is shown with curves for Common, Open and Normal Mode impedances measured along two conductors. Common Mode Iimpedance is the impedance of EMI noise conducted in the same direction along two conductors. Open Circuit Impedance is the impedance measured across a single leg of the common mode choke. Normal Mode Impedance is the total impedance to the differential circuit (both out and back). Tested with: ·HP4396A (100KHz - 1.8 GHz) or HP8753 (to 6 GHz) Network/Spectrum analyzer ·HP43961A Impedance Test Kit ·HP16192A Test Fixture or Inter-Continental Microwave custom fixtures ·HP16200A DC Bias Adapter ·Philips PM2811 DC Power Supply ·Ambient Temperature 23.5oC + 2o ·Bandwidth 3 kHz ·Sweep Time 423 ms ·Impedance is rated at + 25%@100MHz PART NUMBERING SYSTEM CM PRODUCT SERIES CODE 4545 X 800 B PART SIZE CODE RATED CURRENT CODE IMPEDANCE VALUE CODE - PACKAGING CODE 00 ADDITIONAL DESCRIPTION Ambient Operating Temperature Range: -55° C to +125° C IMPEDANCE (Z) TYPICAL OHMS @ 100MHz 500MHz 1GHz DCR MAX OHMS RATED I MAX ( continuous ) mA 2.54 + 0.10 (0.100 + 0.004) 130 270 230 0.003 10,000 7.62 + 0.10 (0.300 + 0.004) 2.54 + 0.25 (0.100 + 0.010) 130 270 230 0.003 10,000 9.32 + 0.25 (0.367 + 0.010) 7.62 + 0.10 (0.300 + 0.004) 2.54 + 0.10 (0.100 + 0.004) 80 270 210 0.003 10,000 9.32 + 0.25 (0.367 + 0.010) 7.62 + 0.10 (0.300 + 0.004) 2.54 + 0.25 (0.100 + 0.010) 80 270 210 0.003 10,000 Fig # A mm (inches) B mm (inches) C mm (inches) D mm (inches) E mm (inches) CM4545Z131B-00 1 11.38 + 0.25 (0.448 + 0.010) 11.38 + 0.25 (0.448 + 0.010) 9.32 + 0.25 (0.367 + 0.010) 7.62 + 0.10 (0.300 + 0.004) CM4545Z131R-00 2 11.38 + 0.25 (0.448 + 0.010) 11.38 + 0.25 (0.448 + 0.010) 9.32 + 0.25 (0.367 + 0.010) * CM4545X800B-00 1 11.38 + 0.25 (0.448 + 0.010) 11.38 + 0.25 (0.448 + 0.010) * CM4545X800R-00 2 11.38 + 0.25 (0.448 + 0.010) 11.38 + 0.25 (0.448 + 0.010) PART NUMBER High Frequency Material CM4545Z131B&R-00 (2 Turn) Z, R, XL vs. Frequency Impedance, Resistance, Inductive Reactance 500 Impedance (W) 400 300 200 100 XL 0 1 20 CM4545Z131B&R-00 (2 Turn) Z vs. Frequency Open, Common and Normal Mode 600 500 Impedance (W) * 10 100 1000 400 300 Normal 200 Z 100 R 0 Open Common 10000 1 10 100 Frequency (MHz) Frequency (MHz) STEWARD - U.S.A. • Telephone: 423/867-4100 • Fax 423/867-4102 • Internet: http://www.steward.com SCOTLAND • Telephone: 44-(0)1-506-414200 • Fax 44-(0)1-506-410694 SINGAPORE • Telephone: (65)337-9667 • Fax (65)337-9686 1000 10000 CM4545Z131B&R-00 (1 Turn) Z vs. Frequency Open, Common and Normal Mode 700 600 600 500 500 Impedance (W) 700 400 300 Z 200 R 100 0 400 300 Open 200 Common Normal 100 XL 0 1 10 1000 100 1 10000 10 1200 1200 1000 1000 Impedance (W) Impedance (W) CM4545X800B&R-00 (2 Turn) Z, R, XL vs. Frequency Impedance, Resistance, Inductive Reactance 800 600 Z 400 200 XL 0 10 100 10000 CM4545X800B&R-00 (2Turn) Z vs. Frequency Open, Common and Normal Mode 800 600 400 Normal Open Common 0 1000 10000 1 10 Frequency (MHz) CM4545X800B&R-00 (1 Turn) Z, R, XL vs. Frequency Impedance, Resistance, Inductive Reactance 400 1000 200 R 1 100 Frequency (MHz) Frequency (MHz) 100 Frequency (MHz) 1000 10000 CM4545X800B&R-00 (1Turn) Z vs. Frequency Open, Common and Normal Mode 400 300 200 Impedance (W) 300 Impedance (W) COMMON MODE Impedance (W) CM4545Z131B&R-00 (1 Turn) Z, R, XL vs. Frequency Impedance, Resistance, Inductive Reactance Z 100 XL 200 Open Normal 100 Common R 0 0 1 10 100 1000 10000 1 10 100 1000 10000 Frequency (MHz) Frequency (MHz) Recommended Soldering Conditions Land patterns for Reflow soldering One Turn / Two Turn Equivalent Circuits STEWARD - U.S.A. • Telephone: 423/867-4100 • Fax 423/867-4102 • Internet: http://www.steward.com SCOTLAND • Telephone: 44-(0)1-506-414200 • Fax 44-(0)1-506-410694 SINGAPORE • Telephone: (65)337-9667 • Fax (65)337-9686 21
