CSA0603C0G330J500JT 为 HRE(芯声)出品的一款贴片多层陶瓷电容(MLCC),容量 33 pF,精度 ±5%(J),额定电压 50 V,介质为 C0G(又称 NP0),封装 0603(约 1.6 mm × 0.8 mm)。该系列以温度特性稳定、损耗低、频率特性优异为主要卖点,适用于对精度和稳定性要求较高的模拟、射频及时钟电路。
主要特性:
C0G 介质提供接近理想电容的温度响应和极低的介电损耗,33 pF 的小容量在 0603 封装下具有较高的自谐频率,适合 MHz 乃至更高频段的信号处理。与高介电常数介质(如 X7R、X5R)相比,C0G 在频率、温度和时间上的稳定性明显优越,但单位体积下的最大容量较低。
总结:CSA0603C0G330J500JT 是一款面向精密与高频场合的高稳定性 MLCC,凭借 C0G 介质的低损耗与优良温度特性,适用于对时间稳定性、频率响应和低噪声有较高要求的电子系统。购买与设计前建议参考 HRE 的详细数据表以获得完整的机械、电气与可靠性规范。

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.
