HR2220V801R-10 概述
Ferrite beads are passive EMC components that use lossy ferrite material to dissipate high-frequency noise as heat. They behave as frequency-dependent resistors: at low frequencies they appear nearly transparent, while at high frequencies (typically above a few tens of MHz) their impedance rises sharply, attenuating common-mode and differential-mode noise on power rails. The 'high-bias retention' construction maintains the rated impedance even when the bead is subjected to strong DC bias current, making it ideal for high-current power rails where conventional ferrite beads would saturate and lose attenuation.
Key electrical specifications include 800 Ω nominal impedance at 100 MHz test frequency, 8 A continuous current rating, 10 mΩ maximum DC resistance, and operating temperature from -55 °C to +125 °C. The 2220 EIA footprint (5.6 mm × 5.0 mm) enables compact PCB implementation, while the monolithic multilayer construction provides mechanical robustness and consistent electrical performance.
This part is engineered for power-rail filtering in telecom equipment, industrial control modules, and automotive electronic control units where high-bias immunity is critical. The 8 A current rating comfortably supports processor cores, FPGA banks, and high-current POL converter outputs without saturation. Designers frequently pair this bead with bulk-decoupling capacitors to form a π-filter that combines high-frequency attenuation with low-frequency energy storage.
When designing with the HR2220V801R-10, ensure the working current remains below 80% of 8 A under worst-case temperature to avoid saturation-induced impedance loss. Place the bead as close to the connector entry or switching node as practical, with the ground return path kept short to maximize common-mode choke effectiveness.

典型应用
HR2220V801R-10 适用于 6 应用s: DC Power Rail EMI Filtering, FPGA / Processor Core Power Filtering, Industrial Control Module Power Filtering, Telecom Base-Station Power Distribution, Automotive ECU Power-Line Filtering, USB-PD and High-Speed Data Line Filtering.
DC Power Rail EMI Filtering
The HR2220V801R-10's 800 Ω impedance at 100 MHz and 8 A continuous current rating make it ideal for filtering switching-converter noise on high-current DC power rails. Its high-bias retention construction keeps impedance stable even when the rail carries the full 8 A DC load, so the attenuation does not collapse under operating bias. Place the bead in series between the upstream regulator and the downstream load, with 10 µF + 0.1 µF ceramic shunt capacitors forming a π-filter that delivers >40 dB insertion loss above 30 MHz. Compared with smaller 100 Ω beads, the -10's high impedance improves ripple rejection by 18 dB without sacrificing efficiency. The 2220 footprint keeps the parasitic inductance below 5 nH, preserving attenuation up to 1 GHz.
推荐
FPGA / Processor Core Power Filtering
Modern FPGA and processor cores draw 5–8 A transients at sub-MHz switching frequencies and require clean rails above 30 MHz to meet jitter and emission budgets. The HR2220V801R-10 supplies 800 Ω at 100 MHz and 8 A steady-state, attenuating switching noise from upstream POL converters before it reaches the SoC's sensitive supply pins. The high-bias retention ferrite ensures the impedance does not collapse during core load steps, maintaining >30 dB insertion loss in the 50–300 MHz band where most SoC emissions occur. Using a π-filter topology with two 22 µF ceramics plus the -10 bead typically reduces conducted emissions below CISPR 32 Class B limits without additional shielding.
推荐
Industrial Control Module Power Filtering
Industrial PLC and motor-drive modules operate in noisy 24 V bus environments where common-mode and differential-mode noise from relay coils, solenoids, and motor PWM can couple into sensitive analog signal chains. The HR2220V801R-10's 800 Ω / 100 MHz rating combined with -55 °C to +125 °C operation provides reliable EMI suppression across the full industrial temperature range. Its 8 A continuous rating handles the inrush of downstream 24 V regulators without saturating, while the 10 mΩ DC resistance adds <50 mV drop at full load. Designers typically place the bead at each isolated power entry and on every analog supply branch feeding ADC reference circuits.
推荐
Telecom Base-Station Power Distribution
Telecom base-station power distribution networks carry 5–10 A per rail to RF power amplifiers and baseband processors while needing to meet stringent ETSI EN 300 386 EMC limits. The HR2220V801R-10's high-bias retention keeps the 800 Ω impedance stable under the 8 A DC load, providing >25 dB common-mode rejection in the 30–1000 MHz cellular bands where conducted emissions are most heavily regulated. Its 2220 footprint is pin-compatible with industry-standard high-current ferrite beads, simplifying second-sourcing. The 125 °C rating supports sealed outdoor cabinet designs without thermal derating.
推荐
Automotive ECU Power-Line Filtering
Automotive power buses operate at 12 V or 24 V with high inrush from motors and solenoids, plus broadband noise from LED PWM and CAN bus transceivers. The HR2220V801R-10's 8 A continuous rating and high-bias retention suit direct placement on ECU power inputs feeding MCUs and sensor signal chains. Its -55 °C to +125 °C operating range covers cabin and most under-hood locations; confirm AEC-Q200 status with the Laird FAE for safety-critical applications. The 10 mΩ DCR adds minimal loss at 12 V/8 A (less than 80 mW), preserving efficiency in always-on circuits.
推荐
USB-PD and High-Speed Data Line Filtering
USB Power Delivery 3.1 and other modern interfaces pass high current (5 A at 20 V) and high-speed data on the same connector, with strict EMI requirements on the power lines. The HR2220V801R-10's 800 Ω at 100 MHz attenuation profile is well above the noise spectrum of typical USB-PD controllers, while its 8 A continuous rating handles the full PD current range. Used in a π-filter with two 10 µF ceramics, it delivers >40 dB insertion loss from 30 MHz to 1 GHz without interfering with the CC lines. The 2220 footprint fits easily inside USB-C connector shields.

关键差异点
- Highest DC current rating in 2220 ferrite bead family at 8 A （对比 BLM31PG800SN1L (Murata))

设计说明
At full 8 A load the HR2220V801R-10 dissipates approximately P = I²R = 8² × 0.010 = 0.640 W in steady-state, all of which becomes heat in the 2220 ferrite body. With theta-JA around 60 °C/W for the EIA 2220 footprint on a 1 oz 4-layer PCB, this raises the surface temperature by roughly 38 °C above ambient - no external heatsink required. Estimated: based on 8 A full load and 10 mΩ DCR per the Laird datasheet.
Use the manufacturer's recommended 2220 land pattern: pads of 5.8 mm × 5.2 mm with 0.3 mm solder-mask clearance. Keep the input and output traces short and direct, and avoid routing noisy digital or PWM traces beneath the bead. Ground the PCB thermal copper pour with at least four thermal vias (0.3 mm) to the inner plane to spread heat. Place the bead at least 3 mm away from tall components to allow post-reflow inspection.
Do not exceed 6.4 A continuous current in production to leave 20% headroom over the 8 A rating - sustained operation at the rating can saturate the high-bias ferrite over time and permanently shift the impedance curve. Avoid placing two beads in series within the same signal path; their combined parasitic inductance can create a resonance with downstream decoupling caps that amplifies rather than attenuates noise in the 10–100 MHz band. Always verify the actual measured impedance under DC bias, not the no-bias value.
合规信息
RoHS compliant per Laird product page and all distributor listings. Halogen-free status not explicitly stated in the public datasheet - confirm with Laird FAE if required. AEC-Q200 qualification status not listed; AEC-Q100 is shown as not_applicable since this is a passive component (AEC-Q200 is the relevant passive standard).
