Analog Devices Inc. LTC939CS#TRPBF

Overview

LTC939CS#TRPBF from Analog Devices is a tape-and-reel packaging configuration for surface-mount components, specifying EIA-481-compliant carrier tape, 13" reel with 4" hub, 1000-unit quantity, 8 mm tape width, 4 mm pitch, and C4 pin 1 orientation for SOT-23-3 devices. It ensures high-speed automated placement compatibility and ESD-safe handling.

For engineers reviewing the LTC939CS#TRPBF datasheet, LTC939CS#TRPBF pinout, LTC939CS#TRPBF application, or LTC939CS#TRPBF equivalent, this part defines standardized mechanical delivery parameters-not an active electronic component-but critical for SMT line setup, feeder calibration, static control compliance, and PCB assembly yield optimization.

Technical Context

LTC939CS#TRPBF implements EIA-481 standard tape-and-reel packaging for SOT-23-3 devices, with peel-back strength of 10–100 g at 300 ± 10 mm/min and 175°–180° angle. Pin 1 orientation follows C4 convention-upper-left corner when viewed with sprocket holes facing the observer and feed direction counterclockwise.

The carrier tape uses static-dissipative materials; dry-packed reels ship in moisture barrier bags, while nondrypacked versions use ESD-conductive boxes or conductive bags. Reel dimensions conform to industry-standard 13" diameter with 4" hub, supporting high-volume automated placement systems.

FAQ

What is LTC939CS#TRPBF?

LTC939CS#TRPBF is not an active electronic component but a specific tape-and-reel packaging configuration defined by Analog Devices for SOT-23-3 devices. It specifies EIA-481-compliant 8 mm wide carrier tape, 4 mm pitch, C4 pin 1 orientation, and 1000-unit quantity on a 13" reel with 4" hub-ensuring compatibility with automated placement equipment.

Does LTC939CS#TRPBF include a semiconductor device?

No. LTC939CS#TRPBF refers solely to the packaging format-not the component inside. It describes how a compatible SOT-23-3 device (e.g., a voltage reference or op amp) is delivered: in embossed carrier tape, sealed with cover tape, wound on a 13" reel with 4" hub, and ESD-protected per Analog Devices' specifications.

What does the "C4" pin 1 orientation mean for LTC939CS#TRPBF?

For LTC939CS#TRPBF, C4 orientation means that when the reel is held with round sprocket holes facing the observer and unreeled counterclockwise, Pin 1 of each SOT-23-3 device is located at the upper-left corner of its pocket. This alignment is essential for correct vision-system recognition and placement head pickup.

Is LTC939CS#TRPBF compatible with all SOT-23-3 devices?

LTC939CS#TRPBF is a packaging specification-not a device-specific part number. It applies only to SOT-23-3 devices qualified by Analog Devices for this tape-and-reel configuration. Compatibility depends on physical dimensions, lead coplanarity, and tape pocket depth; always verify against the target device's packaging data sheet.

What ESD protection does LTC939CS#TRPBF provide?

LTC939CS#TRPBF uses static-dissipative carrier and cover tapes. Dry-packed versions ship in moisture barrier bags; nondrypacked versions ship in ESD-conductive boxes or conductive bags. To maintain protection, LTC939CS#TRPBF reels must be opened only at ESD-controlled workstations by trained personnel.
