Description

Cobra 25 Copper PCB in 5000k

The Cobra 25 modules are characterized by a very low supply voltage (Uf). This allows the use in projects with limited Uf, as well as the achievement of almost every other Uf by series connection of several Cobra 25 boards. Thanks to the solid copper core base currents of typ. 3A up to max. 5A are possible! Please note our information on thermal management.

Typical areas of application are very light-intensive applications in which the light distribution is to take place in any desired form over a certain area. The shape of the Cobra 25 boards offers ideal conditions for CLUSTERING and CASCADEABILITY.

Benefits:

- low forward voltage (similar to standard high-power LEDs)
- Realization of light intensive applications in the SELV range
- best possible thermal properties due to copper core base


Solderless PCB with sockets for rigid strands (0.2 - 0.75 mm²).

The Samsung LM301B is currently one of the most efficient LEDs on the market and exceeds the 200lm/W limit.


Easy feeding without soldering! The insulated conductor is simply inserted into the clamping point as far as it will go and automatically fixed securely. Please use solid and stripped wires.

Successful usage of high power LEDs:

Heat management
Applications with high power LEDs need enduring, adequate and plane heat conduction from the first moment of use. It is very important and neccessary to get the heat off the devices to ensure the maximum light output, lifetime and efficiancy.

Drive management
LEDs should be run with a constant current in addition to the manufacturers recommendations. To ensure this we recommend to take constant current power supplies because resistors are always a risk factor in high power LED applications.

EMC protection
LEDs are sensitive against heat and electric charge. Please avoid any kind of short circuits or electric discharge to the illuminant. The chip can be damaged or even destroyed.

Storage / JEDEC level
The storage temperature should be from -30°C up to + 80°C in dry ambience. After opening a sealed bag the content should be mounted rapidly. Once absorbed humidity can be removed by tempering the LEDs in some cases. More information can be found in the manufacturers datasheets or on the manufacturer homepages.

Soldering conditions
Each LED has its own soldering conditions that the user should pay attention to. After the launched lead free processing specifications many standarts have changed. Information about recommended soldering can be found in the manufacturers datasheets or on the manufacturer homepages.



Delivery time

Deliveries within Germany take 2-3 days beginning after receipt of payment, for deliveries to invoice beginning with the shipment, for deliveries to cash on delivery beginning with receipt of order. Payments and incoming orders beyond our business hours let the delivery time begin with the next workday. For deliveries to other EU countries the delivery time may be extended up to 3 weeks. The delivery time is subject to the proper delivery of the logistics company, as far as delivery delays are not caused by us. The validity of the above delivery times requires the availability of the ordered goods from stock at the time the delivery time is beginning.
