CDRH2D18/HPNP-2R2NC 为 Sumida(胜美达)系列电源用贴片功率电感。主要电气参数如下:标称电感值 2.2 μH(公差 ±30%,实际范围约 1.54–2.86 μH);额定电流(Ir)1.9 A;饱和电流(Isat)1.6 A;直流电阻(DCR)48 mΩ;封装尺寸标识为 1212。该器件面向开关稳压器、电源滤波与磁性元件密集的紧凑型电源平台。
若系统需更小纹波或更高保留电感量,可考虑:提高电感值或选择 Isat 更高的型号;若热量是限制因素,可选用更低 DCR 的功率电感。选型时综合考虑体积、价格、电流能力与电感公差。
总结:CDRH2D18/HPNP-2R2NC 是一款适用于常见开关电源滤波与中低功率电源轨的经济型功率电感,设计时应权衡 Isat 与 Ir 的限制并优化 PCB 布局与散热以确保稳定运行。若需更详细的机械尺寸、温升曲线或频率特性,请索取 Sumida 官方数据手册。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
