Now there are a lot of people on the active buzzer and passive buzzer concept is not very clear, here to do a brief introduction, I hope to help you use in the future.

Note that "source" here does not mean power supply. Rather, it refers to the source of the oscillation.

The characteristics of a passive buzzer are:

1 Passive does not have an internal oscillator source, so if you use a DC signal can not make it sound. Must use 2K ~ 5K square wave to drive it

2 sound frequency can be controlled, you can make the effect of the "Doraimi hair Solace".

3 In some special cases, and LED can be multiplexed with a control port

Active buzzer is characterized by:

1 active buzzer with internal oscillation source, so as long as the power will be called!

2 Program control is easy, a microcontroller a high and low level can make it sound, while the passive buzzer can not do.

The weight of each set is about 6g

Use the form for single models, category sourcing, and multi-line BOM requirements.

Product sourcing intelligence

Model, package, availability, and BOM fit reviewed before quotation.

WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.

Electronic component model and package intelligence review on an ESD-safe inspection bench

Model & package intelligence

Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.

BOM matching and alternative component comparison workstation with protected IC samples

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
