Inductor RF Choke 33mH

The Inductor RF Choke 33mH is a fixed inductor with an inductance of 33 mH. An inductor stores energy in a magnetic field and resists changes in current, so it passes DC while blocking or filtering AC signals and noise. The 33 mH value suits low-frequency and audio-range filters, LC circuits and choke applications in labs and hobby projects.

Inductor RF Choke 33mH Specifications

• Inductance: 33 mH (33,000 µH)
• Type: fixed inductor (choke)
• Reactance: about 207 Ω at 1 kHz and about 2.1 kΩ at 10 kHz
• Polarity: none, can be fitted either way round

Inductor RF Choke 33mH Applications

• LC low-pass and band-pass filters in the audio range
• LC resonance experiments (33 mH with 100 nF resonates near 2.8 kHz)
• Blocking AC noise on DC supply lines that feed sensitive circuits
• Physics and electronics lab experiments on inductance and RL time constants
• Tone and filter circuits in audio projects

What's in the Box

• 1 × 33 mH inductor

Tip: High-value inductors are wound with many turns of thin wire, so they have a noticeable DC resistance and a limited current rating. Use this one in signal and filter circuits rather than high-current power converters, and measure its DC resistance with a multimeter if your design depends on it.
