For the Mundorf E-Cap bipolar electrolytic capacitors, a distinction is made between two construction types, "raw" and "plain". In the raw model the foil is etched in order to increase the surface area of the foil. Since the capacitance of a capacitor is proportional to the surface area, larger capacitances can be achieved in this way with the same material costs. The construction size of raw electrolytic capacitors, therefore, is in effect smaller. Bipolar electrolytic capacitors are used where large capacitances are required cheaply (e.g. series resonant circuits, impedance linearization). The higher electrical strength of the etched model allows it to also be used where plain electrolytic capacitors are not electrically strong enough and expensive foil capacitors are not an option.

Our precision matching applies to "pairs". You may request a larger matched group, but it may not be possible. NOTE: capacitors and precision matching are priced and sold individually ("each"). Occasionally, we can not find a matched pair. If this is the case, Customer Service will contact you. We offer three levels of matched pairs: L1-factory tolerance 1% matching; L2-1/2 factory tolerance 1% matching; L3-1/4 factory tolerance 1/2% matching.
