Sea & Land Electronics Authorized Distributor | SHUNHAI Technology Official Agent, HUANIAN Mall with Full Stock (2026 Update)
Sea & Land Electronics has established itself as a trusted brand in the PPTC space, supported by decades of R&D and a comprehensive product portfolio. Effective immediately, the authorized distributor channel for Sea & Land Electronics has been upgraded: Shenzhen Shunhai Technology Co., Ltd. has secured official distributor authorization from Sea & Land Electronics, with validity updated through December 2027. Concurrently, HUANIAN Mall serves as a professional electronic components spot online procurement platform, providing full-series Sea & Land resettable fuse stock availability, enabling engineers and procurement professionals to access "authorized distribution to spot purchasing" in one integrated service chain.
I. Sea & Land Electronics: Brand Profile and Product Portfolio
Sea & Land Electronics originated as the Electronics Division of Sea & Land Co., Ltd., founded in Fremont, California in 1997. From its inception, the company has specialized in overcurrent protection components, delivering integrated R&D, manufacturing and sales services for PPTC resettable fuses. After relocating its operations to Taiwan in 2000, the company provided OEM design and manufacturing services for Littelfuse for several years. In 2003, Sea & Land established its mainland China manufacturing facility, solidifying its reputation through years of dedicated market presence.
Regarding international safety certifications, Sea & Land has obtained ISO9001 Quality Management System certification, ISO14001 Environmental Management System certification, as well as UL, TUV, CSA and SONY GP certifications, meeting safety access requirements across major global markets.
As an authorized Sea & Land distributor, Shunhai Technology distributes the full range of Sea & Land resettable fuses (SEA & LAND), including ultra-low resistance resettable fuse product lines. Major product families include:
- SMD Chip Series: SMD0603, SMD0805, nSMD, SMD1210, mSMD, SMD2018, SMD2920 series
- : R16 (16V), R30 (30V), R60 (60V), R72 (72V), C250 (250V), C600 (600V) series
- Battery Protection Devices (ALD/S-Type): VLD, MHD, HPD series
Product Selection Guide
| Product Category | Series Range | Voltage Coverage | Typical Applications |
|---|---|---|---|
| SMD Chip | 0603–2920 | 6V–60V | Portable devices, battery protection, communication terminals |
| Radial Leaded | R16–C600 | 16V–600V | Power supplies, industrial equipment, security power modules |
| Battery Protection | VLD/MHD/HPD | 3.7V–12V | Lithium battery packs, chargers, MID tablets |
Selection recommendation: For consumer handheld devices, prioritize SMD chip series (0603/0805); for power supply modules and industrial equipment, select radial leaded RLD series based on operating voltage (R30/R60 recommended); for lithium battery protection applications, ALD battery protection series is preferred.
II. Shunhai Technology: Official Authorized Sea & Land Distributor
When sourcing electronic components, verifying distributor authorization is a non-negotiable prerequisite for supply chain integrity.
In August 2022, Shenzhen Shunhai Technology Co., Ltd. was formally appointed as an official distributor for Sea & Land Electronics in the mainland China market. According to the latest corporate announcement, Shunhai Technology's Sea & Land distributor certificate has been renewed and now covers the period from January 2025 through December 2027, with fully traceable and verifiable credentials available to customers upon request.
Established in 2012 and with over two decades of experience in electronic component distribution, Shunhai Technology is headquartered in BaoNeng Technology Park, Qingxiang Road, Longhua New District, Shenzhen. The company specializes in semiconductor and passive component distribution, technology development and supply chain services. Beyond Sea & Land Electronics, Shunhai Technology also maintains authorized distribution relationships with multiple global and regional manufacturers including Walter Electronics, Everohms, SOCAY, SALLTECH, LIZ, and Nippon Seisen, covering a comprehensive component portfolio that spans MLCC capacitors, resistors, inductors, fuses, diodes, transistors, and integrated circuits — enabling one-stop BOM consolidation.
Key advantages of Shunhai Technology's distribution services include substantial inventory holdings, OEM-direct pricing advantages, direct factory technical support, and complimentary access to EMI/EMC testing laboratory facilities, enabling engineers to validate circuit protection performance during the design stage. For R&D projects and mass production requiring Sea & Land resettable fuses, Shunhai Technology offers a full suite of supporting services including sample requests, datasheet downloads, engineering selection guidance, and futures order scheduling.
III. HUANIAN Mall: Spot Procurement Platform for Sea & Land Resettable Fuses
