Electronic components (such as capacitors and inductors) are extremely sensitive to humidity. According to the "Electronic Component Reliability Engineering," when humidity exceeds 60% RH, the corrosion rate of component pins increases threefold, necessitating desiccants with high moisture absorption and chemical stability. Shenzhen Ensobo Desiccant Co., Ltd., a manufacturer and exporter of desiccants for electronic components, offers calcium oxide and molecular sieve desiccants based on different principles for component protection.
Ensobo calcium oxide rapidly absorbs moisture through a chemical reaction (CaO + H₂O = Ca(OH)₂), reducing humidity in a confined space to below 15% RH, making it suitable for short-term moisture protection of electronic components before shipment. Molecular sieves, based on the principle of physical adsorption, selectively absorb water molecules through their porous structure (specific surface area ≥ 700 m²/g). Their performance is stable within a temperature range of -20°C to 80°C, making them suitable for long-term storage of electronic components. Both products have passed electronic-grade material purity testing (impurity content ≤ 0.1%). Shenzhen Ensobo's products have received US UL 94 flame retardant certification and are already used by electronic component suppliers such as Intel and Samsung. The company also offers OEM/ODM services, customizing calcium oxide and molecular sieve packaging (e.g., 0.5g sachets, 5g cans) based on the electronic component's packaging format (e.g., SMD, DIP) and storage cycle. This differentiated adaptation of its application principles provides a scientific solution for moisture-proofing electronic components.
