MODEL LC SERIES NEW PRODUCT Low Pass Filter Leadless Surface Mount Chip Inductor/Capacitors LOW PASS FILTER TECHNOLOGY LC and RC filters are offered by BI to solve issues of unwanted noise. Each has cost/performance trade offs. Thick film RC is the lowest cost and provides good performance. LC composite construction has superior performance through the entire frequency range and has the sharpest roll off compared with RCs. Thin film RC offers good performance (under 1GHz), moderate cost and very good multi-element density. APPLICATIONS • EMI/RFI filtering • On-board controllers and ethernet • Digital communications: facsimile machines, modems and ISDN • Digital AV equipment: television, video camrecorders and DVD • LAN, WAN, universal serial bus cards and graphics card • Computers and peripherals FEATURES AND BENEFITS • Integrated ladder filter • Small outline 0805 and 1206 sizes • Low profile suitable for PCMCIA cards • Nickel barrier terminations • Monolithic construction • Steep insertion loss • Eliminates noise over a wide frequency range • Requires no chip orientation • Ideal for high frequency, space limited designs Specifications subject to change without notice. 4-43 Model LC Series 4 TYPICAL PERFORMANCE - MODEL LC 0805 0 -10 Insertion Loss [dB] -20 LC 0805 L 103M LC 0805 L 223M LC 0805 L 473M LC 0805 L 104M LC 0805 L 224M -30 -40 -50 -60 0.1 1 10 100 1,000 10,000 Frequency [MHz] Cutoff Frequency (Code) 103 223 Temperature Characteristics Meets cutoff frequency 200nH 180nH 2.5 Capacitance at 1MHz 1.8 600pF 300pF 70nH 1.4 2.2 2.7 100pF 30pF 15pF 1.9% 2.3% 1.5 Ω 1.2 Ω ≤5.0% 2.4% 1.8% 1.9% ≤6.0 Ω DC Resistance (Reference) 110nH Meets cutoff frequency Dissipation Factor at 1MHz (Reference) 200nH ≤3.0 Magnetic Loss at 1MHz (Reference) 224 +30%, -20% Inductance at 1MHz (Reference) 104 -25°C to +85°C (Tolerance) (Reference) 473 3.0 Ω 1.8 Ω 4-44 1.8 Ω Model LC Series TYPICAL PERFORMANCE - MODEL LC 1206 0 -10 Insertion Loss [dB] -20 LC 1206 L 103M LC 1206 L 223M LC 1206 L 473M LC 1206 L 104M -30 -40 4 -50 -60 0.1 1 10 100 1,000 10,000 Frequency [MHz] Cutoff Frequency (Code) 103 223 Temperature Characteristics +30%, -20% Inductance at 1MHz Meets cutoff frequency 330nH 550nH 1.1 Capacitance at 1MHz (Reference) 1.0 1.5 0.6 760pF 200pF 100pF 20pF ≤5.0% 3.0% 1.7% 2.0% 2.3% ≤6.0 Ω DC Resistance (Reference) 150nH Meets cutoff frequency Dissipation Factor at 1MHz (Reference) 220nH ≤3.0 Magnetic Loss at 1MHz (Reference) 104 -25°C to +85°C (Tolerance) (Reference) 473 2.6 Ω 4-45 1.9 Ω 1.4 Ω 1.4 Ω Model LC Series ELECTRICAL Part Number LC 0805 L 103M LC 1206 L 103M LC 0805 L 223M LC 1206 L/H 223M LC 0805 L/H 473M LC 1206 L/H 473M LC 0805 L/H 104M LC 1206 L/H 104M LC 0805 L/H 224M Cutoff Frequency -3dB (±20%) 10 MHz 10 MHz 22 MHz 22 MHz 47 MHz 47 MHz 100 MHz 100 MHz 220 MHz Rated Voltage 25Vdc 25Vdc 25Vdc 25Vdc 25Vdc 25Vdc 25Vdc 25Vdc 25Vdc Rated Current Max. 100mA dc 100mA dc 100mA dc 100mA dc/1A dc 100mA dc/1A dc 100mA dc/1A dc 100mA dc/1A dc 100mA dc/1A dc 100mA dc/1A dc DCR Max. 6 Ohms 6 Ohms 6 Ohms 6 Ohms/1 Ohm 6 Ohms/1 Ohm 6 Ohms/1 Ohm 6 Ohms/1 Ohm 6 Ohms/1 Ohm 6 Ohms/1 Ohm FILTER DESIGN COMPARISON AND BENEFITS Low pass filters are most commonly used in high frequency circuits where the probability of noise is significant. is superior to discrete solutions at high frequencies due to very short internal interconnections. The LC Series' ladder construction is superior to "T" styles by offering greater attenuation beyond the cutoff frequency. The LC Series, a ladder type low pass filter, is the most suitable for attenuating unwanted noise. The LC Series is an integrated passive device with the equivalent of four inductors and three capacitors imbedded into a single 0805 or 1206 monolithic chip. The LC Series integrated passive ladder construction The LC Series low pass filters offer steeper insertion loss and greater noise attenuation than other filters. The LC Series provides signal attenuation below -20dB above 1GHz.
