What are the key features of 744741222?
- High 2200 µH inductance on a nickel-zinc core provides effective EMI filtering and energy storage in low-frequency power circuits
- Radial-leaded cylindrical package with 5 mm lead spacing and 0.65 mm lead diameter fits standard PCB hole patterns for easy through-hole assembly
- DC resistance of 11 Ω limits high-frequency ripple current, making this inductor effective as a line filter choke in low-current power supply inputs
What is 744741222 used for?
The 744741222 is used as a power line filter choke in AC-DC and DC-DC converter input stages where 2200 µH inductance is needed to attenuate low-frequency conducted EMI below 1 MHz. Its radial through-hole form factor suits prototype boards, industrial control units, and audio equipment where leaded components are preferred over SMT. The nickel-zinc core also makes it suitable for frequency-selective filter networks in signal conditioning and sensor power supply circuits.

Frequently Asked Questions
What inductance and DC resistance does the 744741222 provide for power filtering applications?
The 744741222 provides a nominal inductance of 2200 µH and a DC resistance of 11 Ω, making it suitable as a line filter choke for conducted EMI suppression at frequencies up to several hundred kHz in low-current power supply input stages.
What core material is used in the 744741222 and how does it influence frequency performance?
The 744741222 uses a nickel-zinc (Ni-Zn) ferrite core, which maintains useful permeability from below 100 kHz up to several megahertz. This makes it effective for EMI filtering in the 100 kHz to 1 MHz range, unlike manganese-zinc cores that saturate at lower frequencies.
How does the radial-leaded package of the 744741222 simplify PCB integration?
The radial-leaded cylindrical package has a 5 mm lead spacing and 0.65 mm lead diameter, matching standard 5 mm pitch PCB hole patterns. Leads extend 5 mm from the body, allowing straightforward insertion into through-hole PCBs by hand or with automated insertion equipment without custom footprint modifications.
For which low-current filtering scenarios is the 744741222 more appropriate than a smaller inductance value?
The 2200 µH inductance of the 744741222 is appropriate when the power supply input requires attenuation of conducted noise below 50 kHz or when forming an LC filter with a large capacitor to achieve a corner frequency below 1 kHz, such as in audio equipment power rails, precision sensor supplies, or industrial 24 V bus filters carrying less than 50 mA continuous current within the 11 Ω DC resistance budget.
