The part can sit on a board in an engine-bay ECU or an outdoor radio head without derating the temperature spec. The E case is the larger body in the TPS series, carrying the 680 µF / 4 V rating without the ESR penalty of a smaller case. ## TPS series — what the family tells you The TPS series from KYOCERA AVX is a low-ESR molded tantalum line positioned for power-supply decoupling and filtering applications where standard tantalums would run hot. The molded case gives consistent dimensions for pick-and-place and good mechanical stability under reflow. Tape & Reel packaging means the part ships on 13-inch or 7-inch reels for automated assembly — no tube or bulk tray handling needed for volume production.","metaTitle":"KYOCERA AVX TPSE687K004R0040 Tantalum Cap, 680 µF, 4 V","metaDescription":"Active KYOCERA AVX TPSE687K004R0040 tantalum capacitor, 680 µF, 4 V, 40 mOhm ESR, ±10%, -55°C to 125°C, 2917 package.

This is the equivalent series resistance that determines how much AC ripple current the capacitor can handle before self-heating becomes a problem. For a 680 µF tantalum at 4 V, 40 mOhm is a low-ESR grade — it can sit on a switching regulator output without overheating."},{"question":"What package and footprint does TPSE687K004R0040 use?","answer":"2917 (7343 Metric) surface-mount case, size code E.
