Q1: What are the main features of KEMET T491X477K010AT?
A: T491X477K010AT is a molded MnO2 tantalum capacitor with 470 uF capacitance, ±10% tolerance, and 10 VDC rated voltage. It uses a 2917 surface mount package measuring approximately 7.3 mm x 4.3 mm, with 200 mOhm ESR. The operating temperature range is -55 to +125 degrees C, and the component is RoHS compliant and supplied in tape and reel packaging.
Q2: What is KEMET T491X477K010AT used for?
A: This capacitor is commonly used for power supply filtering, bulk decoupling, voltage stabilization, and energy buffering in electronic circuits. It can be used in power management circuits, telecommunications equipment, industrial controls, embedded systems, and other applications requiring 470 uF capacitance in a compact surface mount package. The 200 mOhm ESR also makes it suitable for applications where controlled ripple and transient response are important.
Q3: Does T491X477K010AT have any alternative manufacturer and part number?
A: Yes. Possible alternatives include Vishay Sprague 293D477X9010E2TE3 and 293D477X9010E2WE3, which are listed as direct substitutes by a major distributor. KEMET T510X477K010ATE035 is another listed direct substitute, while KEMET T491X477M010AT and KYOCERA AVX TAJE477K010RNJ are listed as similar products. However, alternatives should not be treated as automatically interchangeable. Capacitance, voltage rating, tolerance, ESR, leakage current, package dimensions, termination style, ripple current, temperature characteristics, and circuit requirements should all be checked before substitution.
Q4: Is technical support available for KEMET T491X477K010AT?
A: Yes. Technical support can cover capacitor selection, voltage derating, ESR, ripple current, leakage current, PCB mounting, polarity, operating temperature, and replacement evaluation. Nantian Electronics can also provide T491X477K010AT parameters, datasheet information, pin and package information, quotation, and purchasing support.
