Overview

The TLJR476M010R3200 is a solid tantalum capacitor from AVX Corp/Kyocera Corp, designed for reliable bulk capacitance and decoupling in compact electronic equipment. As a member of a molded surface-mount tantalum capacitor family, it offers stable capacitance over temperature, low leakage current, and good long-term reliability compared with aluminum electrolytics of similar size. Devices in this series are commonly used on low-voltage rails (around the 10 V class) for smoothing DC supplies, bypassing noise, and providing local energy storage next to ICs such as microcontrollers, FPGAs, and communication devices.

The capacitor is intended for reflow-soldered PCB assemblies and is suitable for general-purpose, industrial, and consumer-grade designs that require a space-efficient, polarized capacitor with predictable impedance and ESR characteristics. Exact capacitance, voltage rating, case size, and ESR values should be confirmed in the TLJ series datasheet or the specific TLJR476M010R3200 product documentation.

Applications

• Input and output filtering in DC/DC converters and low-voltage power supplies
• Decoupling and bulk capacitance on digital logic, microcontroller, and FPGA power rails
• Energy storage and smoothing in consumer electronics such as set‑top boxes, TVs, and audio equipment
• Bypass and filtering in industrial control modules, PLC I/O cards, and sensor interface boards
• Power rail stabilization in communication equipment, networking devices, and baseband boards
• General-purpose use in compact, battery-powered or handheld electronics where stable capacitance is required

Alternatives & Replacement

Depending on stock levels, lifecycle status, cost targets, or updated design requirements, it may be necessary to consider alternative tantalum capacitors with comparable capacitance, voltage rating, ESR, and case size. Suitable replacements should be evaluated both electrically and mechanically to ensure they meet the original design intent.

Recommended alternatives:

• Kemet T491B107M010AT – surface-mount tantalum capacitor, redesign may be required (view details)
• AVX Corp/Kyocera Corp TAJC686K016RNJ – same manufacturer, different value/voltage, redesign may be required (view details)
• Kemet T491A474K025AT – alternative value/voltage in T491 series (view details)
• Kemet T491A225K035AT – higher voltage rating option, board changes likely (view details)
• AVX Corporation TAJT226M010RNJ – tantalum capacitor with similar voltage class (view details)
• Vishay 293D476X9016C2TE3 – Vishay molded tantalum series, redesign required (view details)

Engineering note: All listed alternatives have been identified with a “Redesign Required” grade, meaning they are not drop‑in replacements. Before committing to any substitute, verify the detailed datasheets for capacitance, voltage rating, tolerance, ESR, ripple current capability, case size, pad layout, and derating guidelines. Pay particular attention to polarity marking and footprint geometry to avoid PCB rework or reliability issues.
