High Current Feedthru Capacitors W2H/W3H Series GENERAL DESCRIPTION MECHANICAL CHARACTERISTICS High current feedthru capacitors are designed as a broadband EMI filter that is specially designed to have high current handling capability. These SMT feedthru filters offer an optimized frequency response with high attenuation across a wide RF spectrum due to optimized parallel and series inductances. These W2H/W3H feedthru filters can actually replace discrete L/C filter networks. • Available in EIA 0805 and 0612 cases • Plated Tin over Nickel Barrier • Packaged in Tape & Reel FEATURES • Low parallel inductance provides significant noise reduction in circuits with operating frequencies up to 5GHz • Broad frequency response with high attenuation • High rated current – up to 2A for 0805 and up to 5A for 0612 • Small size – 0805 and 0612 case size • Reeling in accordance with EIA-481 TYPICAL APPLICATIONS • • • • • High current power (Vcc) lines PA decoupling DC:DC converters Regulators Power supervisory circuits HOW TO ORDER W2H1 5 C 473 8 A T 1A Size & Style W2H1=0805 W3H1=0612 Voltage 3=25v 5=50v 1=100v Dielectric A=NP0 C=X7R Capacitance Code Capacitance Tolerance 8=+50/-20% M=±20% Failure Rate A=Not Applicable Terminations T=Plated Ni And Sn Packaging 1A=7" Reel 4000 pcs 3A=13" Reel 4000 pcs PINOUT CONFIGURATION Signal/Vcc Ground Signal/Vcc Signal/Vcc Ground Ground Ground Signal/Vcc W2H1 – 0805 Style W3H1 – 0612 Style 5 High Current Feedthru Capacitors W2H/W3H Series ELECTRICAL PARAMETERS Insulation Resistance DC Resistance Operating Temperature 1000 mOhms Minimum <150 mOhms -55C to +125C CAPACITOR VALUES Part Number W2H13C 104 8AT W2H15C 473 8AT W2H15C 223 8AT W2H15C 103 8AT W2H15C 102 8AT W2H11A 471 8AT W2H11A 221 8AT W2H11A 101 8AT W2H11A 470 8AT W2H11A 220 8AT W3H13C 104 8AT W3H15C 473 8AT W3H15C 223 8AT W3H15C 103 8AT W3H11A 471 8AT W3H11A 221 8AT W3H11A 101 8AT W3H11A 470 8AT W3H11A 220 8AT 6 Size 0805 0805 0805 0805 0805 0805 0805 0805 0805 0805 0612 0612 0612 0612 0612 0612 0612 0612 0612 Dielectric X7R X7R X7R X7R X7R NP0 NP0 NP0 NP0 NP0 X7R X7R X7R X7R NP0 NP0 NP0 NP0 NP0 Capacitance 100,000pF 47,000pF 22,000pF 10,000pF 1,000pF 470pF 220pF 100pF 47pF 22pF 100,000pF 47,000pF 22,000pF 10,000pF 470pF 220pF 100pF 47pF 22pF Tolerance +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% +50%, -20% Voltage 25V 50V 50V 50V 50V 100V 100V 100V 100V 100V 25V 50V 50V 50V 100V 100V 100V 100V 100V Current 2A 2A 1A 1A 1A 0.5A 0.5A 0.5A 0.5A 0.5A up to 5A up to 5A up to 4A up to 3A up to 4A up to 4A up to 4A up to 3A up to 3A High Current Feedthru Capacitors W2H/W3H Series PHYSICAL DIMENSIONS AND PAD LAYOUT L T BW C P X T W S S BL EW W L P W2H1 – 0805 Style W X BW P T S W BL EW S T C ES X L L W3H1 – 0612 Style PHYSICAL DIMENSIONS L W W2H1– 0805 MM 2.01 ± 0.20 1.25 ± 0.20 (in.)
