产品特点 FEATURES

Brand: Belfuse; Model: SQ24T15033-PEC0G

1 Input Voltage Range: 18-36 VDC (continuous max 40 VDC)

2 Output Specifications: 3.3 VDC nominal, up to 15 A output current; adjustable via trim pin (-20% to +10% of nominal)

3 High Efficiency: Up to 88% (at 25°C, 300 LFM airflow), eliminating the need for external heat sinks

4 Compact & Low Profile: Size is 60% of standard quarter-bricks, reducing airflow shadowing for downstream components

5 Remote Sense Function: Compensates for voltage drops between converter and load to ensure stable voltage at the load point

6 Comprehensive Protection: Includes undervoltage lockout (UVLO), overcurrent protection (OCP), overvoltage protection (OVP), overtemperature protection (OTP), and short-circuit protection with auto-restart

7 High Reliability: MTBF of 3.4 million hours (per Telcordia TR-332 Method I Case 1)

8 Compliance: UL/CSA 60950-1 and IEC60950-1 certified; RoHS-compliant (lead-free options available); UL94 V-0 flammability rating

9 Installation Options: Through-hole (SQ24T) or surface mount (SQ24S) packages

10 Wide Operating Temperature: -40°C to 85°C

使用场景 APPLICATIONS

1 Telecom Infrastructure: Powering transceivers, baseband units, and network switches in 24V/36V battery-backed systems

2 Industrial Automation: Providing stable 3.3V power to PLCs, HMIs, sensors, and actuators

3 Data Center Equipment: Converting bus power (24V/36V) to 3.3V for server CPUs, memory, and storage controllers

4 Embedded & IoT Devices: Compact design ideal for IoT gateways, industrial PCs, and medical diagnostic equipment

5 Networking Hardware: High-speed routers, switches, and access points requiring space efficiency

注意事项 PRECAUTIONS

1 Input Voltage: Do not exceed 40 VDC (absolute max) or operate below 18 VDC

2 Remote Sense: Connect to load terminals for voltage compensation; short to Vout pins if unused

3 Trim Adjustment: For 3.3V output, limit to -20% to +10% to maintain OVP functionality

4 Temperature Derating: Reduce load current at ambient temps above 25°C (refer to derating curves)

5 Protection Triggers: Auto-restart after faults; remove fault condition before resuming operation

6 Installation: Follow recommended pad dimensions for surface mount; handle with ESD protection

7 Safety Compliance: Adhere to UL/CSA/IEC standards for safe operation
