这款由谱罗德(PROD)推出的PSPMAA0803H-330M-ANP贴片功率电感,是针对中低功率电源场景优化的核心储能元件。其平衡了电感值、电流能力、封装尺寸与成本,广泛适配消费电子、智能穿戴、IoT设备等领域的DC-DC转换需求,是小型化电源设计的实用选择。
作为一款SMD贴片功率电感,该产品的定位清晰指向中低功率、紧凑空间、低损耗的电源应用:
其核心价值在于用紧凑封装实现“持续负载稳定+瞬态尖峰耐受”,满足批量应用的成本与性能平衡。
参数是功率电感性能的核心,以下结合应用场景拆解关键指标:
33uH属于中值功率电感,适配100kHz-1MHz的常见DC-DC开关频率(消费电子电源主流设计):
指电感连续工作时的最大均方根电流,此时电感温升控制在安全范围(行业标准通常≤40℃):
是电感铁芯饱和时的电流阈值(电感值下降约30%的临界点):
是电感绕组的直流电阻,直接影响铜损(损耗公式:P=I²R):
该电感采用SMD贴片封装,具体尺寸为8.0×8.5×3.0mm(长×宽×高),具备以下优势:
PROD谱罗德PSPMAA0803H-330M-ANP功率电感,以33uH中值电感、2.5A额定电流、4A饱和电流、180mΩ低DCR为核心,结合8mm级紧凑SMD封装,实现了“性能-成本-空间”的三维平衡。其广泛适配消费电子、智能穿戴、IoT等中低功率场景,是小型化电源设计的高性价比选择。

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.
