This vertical-mount toroid features a nominal inductance of 33 µH ±15% measured at 1 kHz, with an inductance of 22.8 µH ±15% under rated DC bias current conditions. The component supports a maximum DC current (Idc) of 5.0 A, defined as the current causing a maximum 30°C temperature rise, and exhibits a maximum DC resistance (DCR) of 0.029 Ω. The toroidal construction utilizing ferrite core material delivers low radiation characteristics, low core losses, and high current capacity, making it suitable for switch-mode power supplies, noise suppression networks, and energy storage applications in industrial and commercial equipment. Physical dimensions for the 2107-V-RC include a nominal outer diameter (Dim. A) of 0.32 inches, mounting height (Dim. B) of 0.75 inches, and lead spacing (Dim. C) of 0.034 inches. The vertical mounting configuration (-V suffix) positions the toroid perpendicular to the PCB, with leads tinned to within 0.062 inches above the mounting plane and 0.5 inch maximum lead length. The component operates across an extended temperature range of -55°C to +105°C, accommodating demanding thermal environments. The -RC suffix denotes RoHS compliance, and the through-hole package style ensures robust mechanical attachment for high-vibration applications. Engineers selecting this inductor should verify actual performance in their specific circuit topology, noting that inductance characteristics under DC bias and temperature conditions must be evaluated against converter switching frequency and ripple current requirements. ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (21-Jan-2025) | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:4726694/) ## **Hi h Current Toroid Inductors g** ## _**Special Features**_ - DC/DC converter, EMI fi lter applications - Low radiation - Low core loss - High current capacity - Horizontal or vertical mount - Low cost - Operating temperature -55 to +105 °C ## _**Notes**_ * Current to cause 30 °C max. temperature rise ** Insert -H or -V for mounting style before -RC _Example: 2113-V-RC_ _† RoHS Directive 2002/95/EC Jan 27 2003 including Annex._ **==> picture [272 x 48] intentionally omitted <==** **----- Start of picture text -----**
