Aiphone NP-25V Non-Polarized Capacitor, 33mF, 25V for Intercom Call Tone Circuits
The Aiphone NP-25V is a non-polarized capacitor rated at 33 microfarad and 25 volt, engineered as a component-level accessory for Aiphone electronic access control and intercom systems. This capacitor blocks DC voltage from passing through the circuit, preventing unwanted shorts that can trigger false call tone activation. Built for commercial door hardware and access control applications, the NP-25V is a precision electronic component designed to maintain reliable signal integrity within compatible intercom wiring configurations.
Key Features
- DC Voltage Blocking: Blocks DC voltage from passing through the circuit, preventing unwanted short circuits that can cause unintended call tone activation.
- Non-Polarized Design: Non-polarized construction allows installation without concern for orientation, simplifying wiring and reducing installation errors.
- Precise Electrical Rating: Rated at 33 microfarad and 25 volt for consistent, predictable performance within compatible Aiphone intercom and access control circuits.
- Electronic Component for Access Control Systems: Purpose-built as a replacement or supplemental part for Aiphone electronic access control installations, supporting reliable long-term circuit operation.
- Commercial-Grade Application: Designed for use in commercial door hardware and access control environments where consistent signal performance is essential.

Aiphone AIP-NP-25V-NP – Frequently Asked Questions
1) What does the Aiphone NP-25V capacitor actually do in an intercom circuit?
The NP-25V is a non-polarized 33 microfarad, 25 volt capacitor that blocks DC voltage from passing through the circuit. Blocking that DC path is what stops the unwanted shorts that make a call tone fire on its own. If you have an Aiphone intercom sounding phantom call tones, this is the component that addresses that condition at the wiring level.
2) I am an integrator troubleshooting random door station call tones on an Aiphone system. Is a capacitor the right fix?
If the tone is being triggered by DC voltage finding a path it should not have, yes. The NP-25V is built for exactly that failure mode: it blocks DC through the circuit so a short cannot register as a call. It is a component-level accessory, not a module or a board, so it goes into the wiring run itself rather than replacing a station.
3) Does the Aiphone NP-25V capacitor have to be wired in a particular direction?
No. It is non-polarized, so there is no positive or negative leg to get backwards. You can land it either way round in the circuit, which is one less thing to get wrong on a call-tone wiring correction in the field.
4) Is the 33mF 25V rating on the NP-25V something I can substitute with a generic capacitor from an electronics supplier?
The NP-25V is specified as a non-polarized 33 microfarad, 25 volt part supplied by Aiphone for its own access control and intercom circuits. The value and the non-polarized construction are what make it work in the call tone circuit, so any replacement has to match both. Aiphone supplies it as a genuine component to keep the rest of the intercom installation on spec.
5) Is the Aiphone NP-25V a commercial-grade part or is it for residential intercoms?
It is classified commercial. Aiphone lists the NP-25V for commercial door hardware and access control environments, and typical installs include office buildings, schools, healthcare facilities, retail, industrial access control, multi-tenant residential properties, and government buildings. Multi-tenant apartment entry systems are squarely in scope even though the part itself is a commercial classification.
6) How is the NP-25V ordered, as a single component or part of a kit?
It is sold as a single model, NP-25V, with no size, voltage, or finish options to pick. One part number covers it. Property managers stocking spares for a building with several Aiphone entry panels can order multiples of the same item with no configuration decisions.
