The largest caps I have currently that need testing are 200v 680uf --- End quote --- Oh piddly little ones. ST42 SMD tweezers have no problem with 3900uF. |

ESR is not the most important parameter. But if it's enough for you, you can use the DE5000 to measure ESR any large-capacity capacitor at any frequency in Rs mode. For example, 18000uF at 100 kHz. |

If you want one of the best capacitor testers, look for the Sencore LC103 But unfortunately the used prices these days are higher than the original Sencore list price. |

Is the capacitor bad, does it need to be removed from the circuit or both? I hit the 0.3uF lower limit too often. --- End quote --- How often do you find < 0.3 uF caps that are high in ESR or low in capacitance? In my experience ceramic and film caps are way more reliable than aluminium electrolytics. |
