Key Features
- 12µH nominal inductance in compact 1812 case for efficient board space utilization
- Ferrite core construction providing stable inductance across RF and power-supply frequency ranges
- 0.6Ω DC resistance rating enabling low conduction loss in continuous-current filter stages
- RoHS-compliant (JESD-609 e3) for use in environmentally regulated end products
- Rectangular moulded body for consistent automated pick-and-place assembly on SMT lines
Applications
The CC453232-120KL is used as an RF choke and EMI filter in power supply input stages where a 12µH inductance is required to attenuate high-frequency switching noise across 1MHz to 100MHz. Its 1812 footprint and 0.6Ω DC resistance suit DC-DC converter output filters and power-line decoupling networks in telecommunications and industrial equipment. The ferrite core maintains useful inductance at signal frequencies, making it appropriate for bias-tee circuits and antenna feed networks in radio-frequency front-ends.

Frequently Asked Questions
What inductance and DC resistance does the CC453232-120KL provide, and how do these affect filter design?
The CC453232-120KL has a nominal inductance of 12µH and a DC resistance of 0.6Ω. In a low-pass LC filter operating at 1MHz to 10MHz these values create a cutoff frequency and insertion loss determined primarily by the 12µH inductance and the load impedance, while the 0.6Ω series resistance adds a modest voltage drop of 60mV per 100mA of continuous current.
For which PCB footprint is the CC453232-120KL designed, and how does this affect layout options?
The CC453232-120KL uses the 1812 (4.5mm × 3.2mm) SMT case size, which accommodates the larger copper pads needed for the 12µH winding while keeping the overall profile under 3.2mm high. This case size is widely supported by automated pick-and-place equipment and is compatible with standard 1812 land patterns in most PCB CAD libraries, reducing design-entry effort.
How does ferrite core material in the CC453232-120KL behave at high DC bias compared to air-core inductors?
Ferrite cores saturate when DC bias current exceeds the rated saturation current, causing inductance to drop sharply above that threshold. For the CC453232-120KL's 12µH ferrite design, engineers must verify the saturation current rating against the peak current in their circuit; below saturation the ferrite delivers stable 12µH inductance and better Q factor than an equivalently sized air-core inductor at frequencies below 50MHz.
Is the CC453232-120KL compliant with RoHS directives, and what lead-free solder process is compatible?
Yes, the CC453232-120KL carries the JESD-609 e3 code confirming it is lead-free and RoHS compliant. The e3 designation specifies that the termination finish is compatible with SAC305 (Sn-Ag-Cu) solder paste and standard lead-free reflow profiles peaking at 260°C, which is the industry norm for SMT assembly.
